Method Detail

mapValues

public final <R> Stream<R> mapValues(Function<T,R> mapper)

accept

public <R> R accept(ConditionVisitor<T,R> visitor)

Specified by:

accept in interface VisitableCondition<T>

mapValue

protected T mapValue(T value)

This method allows subclasses to alter the value before it is placed into the parameter map. An example of this is when the case insensitive conditions will change a value to upper case.

We do not expose the values stream because we cannot allow subclasses to change the order or number of values.

Parameters:

value - the value

Returns:

the mapped value - in most cases the value is not changed

renderCondition

public abstract String renderCondition(String columnName,
                                       Stream<String> placeholders)
